Hi,

I'm currently running an analysis on a skid and I just want to get an opinion on what is the best way to consider the tie in point, free or anchor..?

Or is there any standard practice that is being used that i'm unaware of.

You need to look at the skid GA's. There is no standard for this. Pipes may be fixed at tie-in points, but equally this may cause undue thermal problems in the skid itself. Weight support only at the skid edge is quite common. Sometiems the tie-in point is an equipment nozzle within the skid, which is a bit more obvious.

Moverz,

Thx for replying.

To be more specific, my case is not for the tie in point within the skid but for the tie in point connecting to external piping. It is free-end upon design, but it will be connected to other piping upon installation.

Hi Fesh
If possible it is always better to put an anchor within skid close to tie-in interface.
Otherwise in piping analysis skid piping need to consider. you can not consider tie in as free point.

In my view the skid should be considered as a complete independent unit. Providing anchor at the boundary is better. For transportation also support at the end of the piping needed. Limit stop with rest which do not allow inward pipe movement also can be considered if the external piping also is designed by the same party. In that case, anchor or any other type of support can be avoided or decided as usual with normal piping. If the skid alone is to be fabricated, then we need to anchor the pipe or provide the allowable force, moment, movement etc to the external piping party. Anchor if possible is the best option which allows the external piping designer to start his work without difficulty.

Thank you for your replies. It really clears some of my taughts on the matter.
